178 THE DESTRUCTIVE INFLUENCE OF 
flocculent sediment at the bottom of the flask, 
amongst the éébris of the cress. On microscopical 
examination (with a 7,th “immersion” objective) 
much altered chlorophyll existed, either dispersed 
or aggregated amongst the other granular matter 
of the sediment, and amongst some of this three 
minute and delicate Protamebe were seen, varying 
in form, and creeping with moderately rapid slug- 
like movements. They contained no nucleus, and 
presented only a few granules in their interior. In 
the same drop of fluid, and also in others subse- 
quently examined, more than a dozen very active 
Monads (goth of an inch in diameter) were seen, 
each provided with a long, rapidly-moving lash by 
which neighbouring granules were freely knocked 
about. There were many smaller motionless and: 
tailless spherules of different sizes, whose body: 
substance presented a similar appearance to that of 
the Monads—and of which they were, in all proba- 
bility, earlier developmental forms. There were also 
several unjointed Bacteria, presenting most rapid 
progressive movements accompanied by quick axial 
rotations. Many Yoru/a corpuscles and other Fun- 
gus “spores” also existed, as well as portions of 
a mycelial filament containing equal segments of 
colourless protoplasm within its thin investing mem- 
brane. (See Fig. 2.)
